Beta readers are volunteers spending hours on your book for free. Send it too early and you burn their goodwill on problems you could have caught yourself — and their feedback all points at things you already knew. Here's the checklist.
Betas are readers, not editors. They're the best possible instrument for reader experience: where they got bored, whom they rooted for, what confused them, whether the ending landed. They are the wrong instrument for craft diagnosis — POV discipline, scene structure, pacing mechanics. Sending a structurally broken book to betas doesn't get the structure fixed; it gets you five people politely describing the same symptom while the cause stays invisible.
So run the craft-level check before the human read. Fix the mechanical problems a diagnostic can catch, then spend your betas — they're a limited resource — on the question only humans can answer: how does it feel to read this book?
The Manuscript Scorecard grades your full manuscript on nine craft metrics, benchmarks it against professionally-edited books, and tells you exactly what to fix first. Free, in minutes.

Almost never. First drafts have problems you can find yourself for free. Spend betas — a limited, goodwill-based resource — on a draft you've already revised once.
Specific, experience-level ones: Where did you put the book down? Which character did you care about least? Was any part confusing? Did the ending satisfy you? Avoid yes/no craft questions they aren't equipped to answer.
Diagnostics and self-revision first, then betas for reader experience, then professional editing on the strongest draft. Cheapest feedback first, most expensive last.
